Yes, I linked to the manufacturer's page for this model in my original post, so I am familiar with their website. The data they provide is lacking compared to most fan manufacturers I've worked with in the past. I tried requesting more data through their form several times, with the first time...
Wasn't sure which forum to post this in, as I could see almost all engineering disciplines using a Thermal Imager. Hopefully it will reach as many eyes as possible here.
I'm looking for a good handheld Thermal Imaging Camera, preferably in the sub-$1000 range that does NOT have WiFi, Bluetooth...
Yeah, that seems more like the right ballpark. If I can get approved to buy one of these low-flow balometer kits, I'll report back with my actual test data when I get it.
AH-HA! Found some small, relatively lower cost vane anemometer/ balometer kits for low flows

Testing with a balometer (if they can work when oriented horizontally?) is probably the best way. They're so expensive though, I'm not sure I can get them to buy one, and if I did it would take awhile.
Hmm would I be able to make a reasonable estimate of the flow rate through a very small...
I would definitely use this equation if I could, but unfortunately I don't have the heat dissipated by the computer either. We've tried to get that info in the past without success, but I could try again.
Yeah, I was thinking the same thing, so I did test it a second time to make sure. Agreed...
Ahhh, this will work, thank you!
To work through this and make sure I have my units properly accounted for, if I solve for volume flow rate (Q), I will get
Q = Power (W) / delta-P (Pa)
using the motor nameplate info (115V, 1.3A) to get power, let's try this out (I'll still go measure actual...
Hi, we have this draft inducer fan cooling a piece of avionics in a simulator as described here https://www.eng-tips.com/threads/reliable-alternative-to-this-fan.526827/. It’s this one...
Ok finally was able to test it yesterday and found that the SP is 1.3" W.C.
The existing fan is 1/30 HP, although Fasco has since changed the motor on that model, and the new ones they sell now have a 1/25 HP motor instead. I know it's a shaded pole motor. Now, how to spec a suitable replacement...
Ahh ok. Yes, I did notice that 2 of the basic controllers would be cheaper than 1 of the advanced controllers.
I think might actually be ok both the pressure and temperature inputs controlling the same output relay (the one that shuts down the computer), as long as I could have separate aux...
The existing fan is this furnace draft inducer https://www.regalrexnord.com/products/blowers/draft-inducer-blowers/round-outlet-shaded-pole-oem-replacement-draft-inducer-blower-115-volts-flange-no-a088 , which is only connected to our system at the fan outlet. The fan inlet draws from the...
Oooo these may fit the bill as well. https://www.greenheck.com/products/air-movement/fans/ceiling-exhaust-fans
I used more Greenheck fans in my previous life in custom industrial HVAC equipment, but I didn't realize they even made this type of little bathroom fart fan. Says they're designed for...
Hi all. I’m looking to replace this furnace draft inducer fan we use for cooling a very expensive avionics computer in a stationary simulator as detailed here. FASCO’s datasheets have no info on CFM or SP that I can find, so it's difficult to know what CFM & SP to look for in a replacement fan...
Hmmm, alrighty...that is true, simple pressure switch and temperature switch in series will do the job.
I just had a meeting with the "higher ups"....apparently equipment cost is not a concern, just my labor cost is...whoops. But they do want the extra features like a second relay to warn when...
